This can be reproduced in both the testing and demo environments. The issue occurs when you run a previous query that has a previous query in one of the panels. The query will immediately time out and go into the small queue. It stays in the small queue indefinitely and never runs. STEPS TO REPRODUCE: 1. Run a simple query by dragging a concept to the first panel / group. 2. Once the query runs, clear the query tool. 3. Drag the query you just ran from previous query to the first panel. 4. Feel free to add other concepts (not required). 5. Run the query. 6. Clear the query tool. 7. Drag the query you just ran from Previous Queries to the Query Name in the Query Tool. 8. Run the query. 9. Notice the timeout message appears saying it is going into the small queue. 10. The query will appear in Previous Queries as INCOMPLETE and WAITING IN QUEUE TO START PROCESS. 11. The query never runs.
